Get ready to blow your competition away! We have abused our 860cc E-TEC motor package for multiple seasons now and it has proven to be a winner! This kit has all sorts of grunt and torque that just keeps on pulling!! In the steep and deep of the Rockies, to the flat lakes of Michigan, this is the motor that just keeps ripping. We all know the E-TEC is a heck of a motor, but with our porting and custom Wossner pistons the E-TEC becomes a real monster! It produces 180 horsepower and over 120 lb/ft of torque with our Stage 2 porting on pump gas. Simply send us your stock cylinder, head and exhaust valves (Blades only please). We will then bore your cylinders, port them, modify your stock head, and machine your exhaust valves.
